Prep Time:
5 minutes
Cook Time:
3–3½ hours
Rest Time:
5 minutes
Total Time:
3 hours 10 minutes
Servings:
4–6
Ingredients
- 2 pounds beef stew meat (chuck or round), cut into 1–1½ inch cubes
- 1 can (10.5 oz) condensed cream of mushroom soup, undiluted
- 1 packet (1 oz) dry onion soup and dip mix
- 1 can (10.5 oz) beef consommé or 1 cup strong beef broth
Optional Seasonings (if desired):
- Freshly ground black pepper, to taste
- ½ teaspoon dried thyme or garlic powder
- 1 tablespoon fresh parsley, chopped, for garnish
Instructions
- Preheat oven to 300°F (150°C). Lightly grease a 9×13-inch glass casserole dish (or similar size with a tight-fitting lid).
- Layer the beef. Spread the raw stew meat evenly in the prepared dish. Do not season.
- Add the flavor builders. Spoon the undiluted cream of mushroom soup over the beef, spreading gently. Evenly sprinkle the dry onion soup mix on top. Pour the beef consommé (or broth) around the edges of the dish.
- Cover tightly. Secure the dish with its lid or with heavy-duty aluminum foil. It is essential to trap the steam — do not uncover during baking.
- Bake low and slow. Place the covered dish in the oven and bake for 3 to 3½ hours. At the 3-hour mark, carefully remove the dish and test a piece of beef — it should fall apart easily with a fork. If not, cover and return to the oven for 20–30 more minutes.
- Rest and serve. Remove from oven and let stand, covered, for 5 minutes. Uncover, stir gently to combine the gravy, and serve hot over mashed potatoes, egg noodles, or rice. Garnish with fresh parsley if desired.
Notes
- For a deeper flavor, use beef chuck and seek out beef consommé (found near canned soups).
- Do not add water or milk to the soup — it needs to be concentrated for the gravy to form correctly.
- Leftover gravy will thicken when chilled; reheat gently with a splash of broth to loosen if needed.
- Make it gluten-free by using gluten-free condensed mushroom soup, gluten-free onion soup mix, and gluten-free beef broth.
